We got married in my home country. Since it was a small wedding and the trip would be a big expense my in laws decided not to come. Perfectly understandable.
A couple of years later we moved to husbands home country and I met the in laws for the first time. That evening the gave us a cheque as a wedding present.
A couple of days later I came back from walking the dogs to find husband and mil had gone out on an errand.
The errand? They took the cheque and opened an account in her name and his. I was left off it. The address printed on the cheques was the pil's address. I have no idea what the idea behind it was. My husband was in the military at the time and if he was sent away I'd have had no access to the account.
When my eldest was born my mil told me the reason for his colic was my milk was bad.
A year later my husband got out of the military and we had to live with them while we got established in their country. One afternoon I was in the kitchen and heard mil complaining about having us there, how inconvenient it was, how we were always underfoot. I talked with mu husband that evening and we decided I would take my son and go back to my home country as this was the only thing we could see to help the situation. After we left my mil went to my husband and asked why I had taken son away close to Christmas. My husband told them we knew it was a big strain on them and we though this was best (grandparent both lived in the house as they were too ill to live on their own anymore).
Mil lied. Said no such conversation had taken place an I obviously just wanted to leave to hurt her. Causes huge problem between my husband and I, almost ended our marriage, truth came out when sil said she had been there and heard the complaints.
There have been lots of other little things over the years. I have nothing to do with her anymore. Life is too short to put up with her crap. Husband and kids keep in touch with her.
